The white-bellied bronze male ( Lonchura leucogastra ), also known as the white-bellied bronze male , is a species from the finch family (Estrildidae). Several subspecies are distinguished. Some authors assign the white-bellied bronze male together with the mountain bronze male to a super species.
description
The white-bellied bronze male reaches a body length of eleven centimeters. There is no sexual dimorphism .
The front head, the throat and the front neck are colored blackish brown to black depending on the subspecies. The back is dark brown, with some subspecies showing white shaft lines. The wing covers and the arm wings are dark brown. The upper tail-coverts are darker than the back. The black-brown hand wings are lined with light brown, while the black-brown tail feathers have yellowish outer hems.
The front chest and sides of the body vary depending on the subspecies between a paler or a darker chocolate brown. The underside of the body is white in the middle. The eye is brown, the upper beak is dark lead gray while the lower beak is a little lighter. The feet and legs are lead gray.
Young birds are a little lighter brown on the upper side than adult birds. They have more indistinct lines on the shaft. The underside of the body is brownish.
Distribution and way of life
The distribution area of the white-bellied bronze male extends from Malaysia to the region of Tavoy (Myanmar) and the south of Thailand . The species is also found in Sumatra , Borneo and the Philippines . The species is very rare in Java . The population found there could be captive refugees.
The habitat of this fine finch are forest edges and clearings. The species has also opened up human habitat and is also found in gardens, on farms and in rice fields. They are usually observed in pairs and in small groups, presumably family groups. However, they often nest in colonies. The diet consists mainly of grass seeds. In addition, they also eat semi-ripe and ripe rice. For this reason, the white-bellied bronze male is classified as an agricultural pest in some regions.
The round nest is preferably created in the thick bush. The clutch consists of three to four eggs. The breeding season is between ten and thirteen days.
attitude
White-bellied bronze males are very rarely offered in the bird trade. However, it cannot be ruled out that the species is occasionally confused with the pointed-tail bronze male . White-bellied bronze males are bred in Europe, but due to the small number of breeding pairs, inbreeding depressions such as poor fertility and poor hatching rates occur.
